"asphalt roofing systems"

This is a metal roof coating & liquid gutter lining project carried out at Oxford Brookes University. The roof was power washed and the gutters cleaned before application. The gutters were treated with Liquasil's rust primer to prevent further rusting, before the seamless, silicone Gutterseal system was applied. The roof was coated with a single coat of Metalseal 20 in Goosewing Grey.

Fossil museum The Etches Collection, in Kimmeridge, Dorset, is protected by a new high-performance roof in keeping with its character, thanks to Glendyne.

The Green Roofs Consultancy report looked to the provision of Green Bio diverse roof to address the need to encourage additional species. The ABG Green Bio diverse Roof System includes a mixture of plug planted sedum, cuttings and seeded annual and perennial wildflowers. ABG Roofdrain was used as a reservoir and drainage base layer to optimise water retention and prevent ponding. Special provisions were made to create hibernicula for local endangered species. The roof will benefit the building by providing additional insulation and reducing noise pollution.The roofs substrate filters out dust and pollutants helping improve the environment nearby

At Polyroof, we take pride in providing innovative liquid roofing solutions that meet the unique needs of our clients. From project conception to completion, our expertise lies in creating high-performance roofing systems that offer both durability and aesthetic appeal.This case study highlights our collaboration with Woodholm, a picturesque property located in Southerness, constrained by the Dumfries & Galloway Council Planning’s “room in the roof” design.The SolutionWoodholm’s owners were determined to create a home that would evolve organically while adhering to the council’s planning regulations. To achieve their vision, they enlisted the services of David Lamb Architectural Services to submit a Planning Application on their behalf, seeking approval for a modification from an existing apex roof design to a curved roof. After going through the rigorous process, the application successfully obtained full Planning Committee approval on 14 February 2017.To realise their desired construction, Woodholm’s owners had a preference for using wood and oak, aiming to incorporate these elements into the design. To accomplish this, they collaborated with Carpenter Oak Woodland, a renowned timber construction company known for their expertise in oak framed structures. The company skillfully designed an oak framed structure that perfectly met the owners’ requirements. By mid-November 2017, Woodholm had a stunning and aesthetically pleasing frame in place.However, finding an ideal roofing solution proved to be a challenging task for Woodholm. Initially considering a zinc roof, they encountered obstacles due to the prohibitive costs and the challenges posed by their maritime environment, as Woodholm is located directly on the shores of the Solway Firth. It was at this point that David Lamb’s initial positive impression of a roofing product caught their attention. Woodholm’s owners approached Polyroof’s simulated metal finishes with their needs and were introduced to the Polyroof technical team. The team guided them through the necessary technical specifications to meet the Scottish Building Warrant for a Warm Roof, ensuring compliance with the required standards.Fortuitously, Woodholm’s owners discovered that Polyroof would be exhibiting at the “Homebuilding & Renovating Show” from 21-22 October 2017. At the event, they had the opportunity to meet the Polyroof team as well as Contractor, Kenny Scott of LK Roofing, Lochmaben. The Woodholm team was highly impressed and reassured by the collective experience, knowledge, and technical expertise demonstrated by Polyroof and LK Roofing. Equally important, they appreciated their ability to attentively listen to and understand their concerns.Following the show, a site meeting was promptly arranged with LK Roofing, allowing all parties to discuss the project in detail. As a result, a comprehensive and competitive quotation was provided, falling comfortably within Woodholm’s budgetary requirements.By early December 2017, Woodholm’s joiner had installed the sub-decking, which served as the foundation for the roofing system. LK Roofing then expertly applied the Alutrix membrane, a high-quality waterproofing layer, providing Woodholm with a watertight working cover.Thanks to our collaborative efforts with Woodholm, the project achieved a seamless integration of their desired curved roof design, wood and oak elements, and our advanced liquid roofing system. Woodholm’s owners were delighted with the final result—a beautiful, organically evolving home that not only met their needs but also exceeded their expectations.At Polyroof, we are dedicated to providing roofing solutions that offer both outstanding performance and stunning aesthetics. The Woodholm case study is a testament to our commitment to delivering innovative products and excellent customer service, tailored to meet the unique requirements of each project.

Really high quality roof lights and great service.

Very efficientCould not fault! Outstanding service, communication was excellent too. Good price for a high quality product. First time for me to use this company but won’t be the last, I am a roofer and do a lot of flat roofs where occasionally we need roof windows (which most merchants don’t stock). To sum up- top quality, top service, very efficient and a fair price. Thank you 😊

A new car park has been constructed near the Hornschuchpromenade in Fürth and covered with an extensive green roof system. The car park has capacity for 380 cars and has been designed by The Max Bögl Group (MBG) with ease of construction, cost efficiency, visual impact and low maintenance in mind. In collaboration with contractors Isobautec, they selected MobiRoof green roof system from Mobilane as the most suitable option to cover the 1300 square metre roof expanse.

Hydrostop AH-25 product was chosen to refurbish 450m2 of roof at the Sacred Heart Primary School in the Bridgeton area of Glasgow. Areas of the roof had been leaking, leading to considerable water damage and disruption to some classrooms. The priority for the roof works was to procure a waterproofing system with minimal hot works that would cause as little disruption to the school’s everyday activities as possible.

Green roofing forms a key part of roof design as part of a model for sustainable living in 21st century London. Barking Riverside is a joint venture project between Bellway Homes and the Homes & Community Agency. It is an element of the Mayor of London’s plan to build 10,800 new homes, retail, transport links and new town facilities in the Barking region of East London.

This project had a wide ranging number of detailing factors to overcome with cladding abutment details and change in levels to be redesigned and encompassed into a system that also drained the roof areas of their historic high levels of standing water. Some of the existing construction build had not taken into account any suitable maintenance of the roof with sections being completely inaccessible and thus reducing the performance of the waterproofing.

Boughton’s Intensive green roof substrate has been successfully trialled in a ground-breaking analysis project at Coventry University assessing the feasibility of ‘greening’ landscapes with ecological beneficial habitats.  With the objective being to research the benefits and plausibility of incorporating green space and wildlife-friendly habitats into heavily built-up areas, Coventry University handpicked Boughton’s Intensive IN1 substrate based on its nutrient content, weight, and the inclusion of a water supply in chambers beneath the sub-base.The majority of green roofs in the UK fall into the ‘extensive’ category and are based on a low growing succulent, Sedum, which only requires a few centimetres of substrate to grow, whilst intensive green roofs provide a deeper soil depth and can support a more complex plant system. To this end, Coventry University wanted to explore the advantages of intensive green roofs, which offer greater biodiversity, often create accessible spaces, and offer the best insulation properties and storm water management. The organisation partnered with SEL Environmental, who provided its intelligent water management systems for the project.Boughton’s Intensive IN1 substrate boasts greater organic content than extensive substrates, meaning it supports larger plants and can be installed at greater depths, varying from 100-500cm. IN1 provides a stable growing medium for wide variety of plants in intensive green roof installations, including green roof lawns, shrubs and trees.Depending on the substrate depth and plant type, permanent irrigation systems (above or below ground) are sometimes installed with this substrate to as a backup for extended dry periods. They are not required for everyday irrigation, as the substrate has the ability to hold onto sufficient moisture during ambient conditions. The project, funded by Knowledge Transfer Partnership (KTP) and headed up by Sophie Barron-West, followed plant growth for four years from 2017, with a break due to Covid 19. Dr Stephen Coupe and Dr Liz Trenchard from the University’s Centre for Agroecology, Water and Resilience (CAWR) offered their research expertise.CAWR’s Dr Stephen Coupe says: “The technical requirements of Boughton IN1 were a big part of why we chose it. We also wanted the chance to get as many wildflowers in the space as possible. The nutrient levels were perfect because it wasn’t too rich. In fact, it was a ‘just right’ formulation that wasn’t going to overstimulate but would also deliver enough nutrients for what we needed. Ultimately it was going to be perfect for long-term sustainable plant growth.”He continues: “Reliability was another consideration because we knew we could get it delivered on site on time and, because of Boughton’s location in Kettering, we weren’t concerned about lead times, so that was a plus. It’s safe to say it was a studied choice.”Ground-breaking resultsAccording to the University, the trial resulted in ground-breaking analysis into how different types of green roofs can be created and maintained, as well as what their benefits would be alongside others in a built-up area.  The project successfully demonstrated the ecological impact of placing retrofit green roofs onto existing infrastructure, even with a focus on wildflower species and a relatively short development time. An independently-conducted ecological survey recorded five insect species that have national and local rarity value, including two species of bee that are deemed ‘nationally scarce’ and ‘nationally rare’. Of 457 preserved specimens taken on the green roofs at Coventry University, a total of 120 different insect species were recorded, including wasps, sawflies, hoverflies, beetles, and as many as 11 species of bee.  Coventry University’s findings revealed that the innovation in green roofs has improved and increased the total constructed habitat for rare insects. Research has also enabled better water management alongside habitat enhancement. This research has been incorporated into SEL’s product range, where green roofs are now used across four sites in Coventry, London, Aylesford and Blackburn. CAWR’s Dr Stephen Coupe said: “Ecology, biodiversity and wildlife are largely forgotten by planners, designers and builders in developments. Most green roofs installed in the UK are based on sedum, and, while there are additional features that can be added to these green roofs to improve biodiversity, they are rarely incorporated. Our findings, using Boughton’s Intensive green roof substrate, are that the retrofit of green roofs is feasible and, more than four years into development, IN1 has supported verifiably diverse green roofs. The plants on these roofs supported several insects that have rarity status in the UK, which is very positive.” Dr Coupe adds: “Whilst it is probable that substrates take many years to develop anything like the maturity comparable to natural soil, after just four years, IN1 went from having no recordable eukaryotes, to a concentration of organisms, including worms, soil mites and rotifers.”  Boughton Business Development Manager, Jason Lock comments: “Boughton was delighted to be part of this groundbreaking project and buoyed by such positive findings. Our products have been used successfully in a number of iconic green roof developments around the country over the years but it was a pleasure to be involved in such an important trial that would deliver verifiable results assessing the potential for green roofs to create new habitats in urban environments and enhancing local ecological diversity. Boughton offers an extensive range of green roof substrates and we welcome any research that helps further innovation around the application of green roofs.” The experiment at Coventry University is ongoing and the team are set to feed back again at the end of the summer about how prolonged dry weather has affected results. Dr Coupe says: “The beauty of this project is that there is no general timeline for a piece of green space. We need funding to support our ongoing investigations but there are options and opportunities for long-term research. It can last for the lifespan of the site and I think we will see really interesting developments. There is no reason why, over time, these green spaces would be indistinguishable from an existing habitat.” Boughton’s portfolio of green roof substrates are specifically engineered for different types of roof greening, both for domestic and commercial projects. A full product specification is available for each of Boughton’s Green Roof Substrates, and other landscaping products, making exact specification simple and straightforward. There’s also a section on each product listed online, titled ‘to specify (copy & paste)’, designed to make your job even easier. To enquire about your next project, contact Boughton by calling (01536) 510515 or email sales@boughton.co.uk.

Bilco UK's CS-50TB Roof Access Hatch provides the perfect solution for roof-top access at Blair Castle, Scotland. The Category A listed building is said to have been constructed in 1269 and has been extensively added to over the years. Maintaining such a historic monument is a massive task. The Atholl Estate employ an army of staff to ensure this iconic property is preserved for future generations. One of the many problems in looking after such a building is the fact that it was not designed with ease of access to the roof in mind.

The purpose:Taylor Wimpey’s Eclipse development was the final phase of the large-scale modernisation and renewal strategy for the London Borough of Walthamstow Forest, known as The Blackhorse Lane Action Plan. Eclipse would offer affordable social and private housing via 500 homes in two six-storey apartment blocks.To help satisfy one of the Plan’s objectives- “to ensure new developments incorporate the highest levels of sustainable design and their impact on climate change is minimised”- we installed green roofs on both blocks. As it was the final development phase, space was limited; time was also an influencing factor in facilitating the tight build programme,avoiding delays, and enabling the client to deliver much-needed new homes.Our solutionTo enable fulfilment of the brief, we recommended our HM-40 Paratech Hot Melt Roofing System as the inverted waterproofing base for the green roof. A fully-bonded system, HM-40 is a robust, durable, and highly flexible monolithic, self-healing hot-melt waterproofing system for protected roofs, green roofs, terraces, and podium decks with a 40-year durability statement. In addition, it is firerated for unrestricted use when covered with a green or ballast roof.Unlike other hot melt systems that use fleeces, the Paratech system incorporates a reinforcement mesh: this allows the system to be rolled out, making waterproofing installation faster, thereby enabling the contractor to lay the top roofing layer of artificial grass and landscaped green roofs. Unfortunately, an on-site compound to store the roofing components was unavailable. We worked closely with T&T Roofing and Taylor Wimpey to ensure deliveries arrived in build sequence for immediate use, but without adversely impacting residents who had already moved into their newhomes.“The features of the flat roof system provided a seamless, issue-free roof installation, with rapid installation time causing minimal disruption. Langley’s technical team was always on hand to provide assistance when necessary, working collaboratively to guarantee a consistent and highquality installation.”

Raithwaite Hall is a 5 star, 45 bed boutique hotel set in 85 acres of wooded valleys within the North Yorkshire Moors National Park. The hotel offers terraced views of the landscape and across the Whitby coastline. A new extension was designed that is built against the hillside with stepped landscaped areas around the new building and an intensive green roof terrace to help blend the structure in with the surrounding gardens.The intensive green roof terrace is installed directly above a new function and dining room and required a specialised design to accommodate the additional loading and provide the necessary drainage for the turf lawn.     By utilising a multi-purpose geocomposite roof drainage board, the green roof system could be achieved to meet the project specific requirements. The ABG Deckdrain 2540S-NW20XUV product offers a lightweight option that delivers the equivalent drainage capacity of 300mm of drainage stone in a 25mm layer that weighs over a 100 times less per square metre. The lightweight drainage layer is supplied in rolls and is fast to install and move into position. The Deckdrain layer includes an integrated filter geotextile bonded to the top of the cuspated core. This prevents the growing media layer from intruding into the drainage void and filters the soil to prevent clogging. The Deckdrain is made from a high strength HDPE core that supports the 200mm deep layer of growing media required for the intensive green roof installation with deeper root systems. The underside of the product is impermeable and provides additional protection to the liquid waterproofing membrane. A green roof surface finish further helps to prolong the lifespan of the waterproofing layer and prevent UV degradation. The large grassed area on the podium also reduces surface water run-off and the grass is protected against waterlogging via the efficient drainage board layer. The shallow drainage build-up required also reduces the height of the steps onto the terrace and the associated cost of stone flags. The completed installation encompasses a 20mm Roofdrain drainage & reservoir board to support a secondary smaller sedum roof area, as well as Deckdrain layers installed for structural drainage to the surfaces around the patio slab and retaining wall areas.ABG provided a full green roof project design, installation and maintenance service for the project.

This was a relatively small installation of under 100 sq metres of asbestos roof coating and metal gutter lining. The asbestos cement roof was first cleaned using a closed box pressure washer, with all waste water being filtered to 2 microns. The cleaned roof was coated using Liquasil's BBA Approved asbestos roof coating system, Asbestoseal. The metal gutter was cleaned and thn treated with SWT (Surface and wet tolerant) corrosion primer. Joints were treated with Non-Sag Sealer and the gutter lined with Liquasil One to provide a seamless lining.

This project had incredibly restricted access, where the client wanted a green roof on an existing bitumen rooftop overlooked by hotel rooms. The M-Trays® had to be transported on a trolley through the hotel kitchens. They were winched onto the roof itself using a genie lift and slotted into position in a matter of hours. Trying to construct a roll-out green roof was impossible, given the restricted access. Installation was fast and effective, taking only a day and giving an instant green roof. M-Tray® dramatically improved the view from the rooms and improved the guests’ experience.

This project in Derbyshire involved treating cut edge corrosion, re-coating the roof and lining the gutters. Products used were * Metalaseal BBA Approved metal roof coating system * SWT Primer (to treat rust in the gutters and cut edges) * Liquasil One and Non-Sag Sealer to line the gutters. The project is covered by the unique Liquasil Latent Defects Guarantee, which is written specifically for Liquasil and underwritten by an A-Rated, Lloyds of London insurer.

Russell Roof Tiles worked closely with the roofing contractor to supply tiles for a rural exemption scheme.

This project, to coat approximately 2000 sq metres of asbestos roof with the BBA Approved Asbestsoeal system is a lesson for all in correct health and safety. Liquasil provides all approved installers with H&S training as standard. This deals with correct use of netting, scaffold, walkways, work platforms and waste water filtration from asbestos roof cleaning. Having already completed 500sq metres on a unit a year previously, the contractor was invited back to complete the rest of the block, which is the best possible endorsement.

A detailed visual and physical inspection, together with core and moisture probe analysis carried out by IKO on the roof, patio and walkway areas, indicated that the waterproofing membrane was in a condition commensurate with the age and the type of the traditional membranes installed. They had become fragile and brittle. The decks were saturated due to water ingress, and natural ageing had played a principle part in the deterioration of the waterproofing system. The build-up would not have met the requirements of the current building regulations Part L. IKO worked to refine the specification for the main roof,

This asbestos cement roof in Norwich was soiled with moss and lichen covering the surface and had leaks in several places. Liquasil's BBA Approved Asbestoseal 20 asbestos roof coating was specified to extend the life of the roof and provide an aesthetically pleasing finish. The Contractor, ID Asbestos Ltd, carried out the works safely and efficiently.After being steam cleaned, the metal fixings were treated with our SWT Corrosion Primer and all fixings and cracks were sealer with Non-Sag Sealer. The whole roof was then coated with Asbestoseal 20 to provide a sleek new finish to the old asbestos sheets.Liquasil's Latent Defects Insurance Guarantee was provided upon completion.

The client contacted us in urgent need of a green roof solution before a project handover. Green roof was part of the planning application. Pre-grown panels with patented design were delivered on pallets and lifted to the roof via forklift. The ingenious connecting system means each module clicks to its neighbour tightly and securely so once installed, the sedum has a seamless appearance. The plants are a mixture of sedum species ideal for the UK climate. They are well rooted into Wallbarn's bespoke substrate and fully mature. 250 sqm of green roof was installed in 1 day.

- Location: The Roof Gardens, Apartments, Manchester - Developer: DeTrafford Estates Group - Challenge: The previous intumescent varnish on external timber panelling on walls and decking broke down after just 12 months. - Solution: Remove existing coating, apply Zeroflame Treatment - Result: Original beauty of the decking and timber paneling on the walls is resorted, the timber is compliant with building regs and the property owner is happy.

This metal roof in Warwick was suffering from cut-edge corrosion, delamination of the factory finish, and spot corrosion.The specification called for a full liquid roof coating in Merlin Grey, which Liquasil was able to supply for installation by Nadco Roofing Services. Liquasil's Metalseal can be made in any RAL or British Standard colour to suit the client's needs.After the corroded surfaces had been prepared back to bare metal and the substrate had been jet-washed and dried, a single coat of Metalseal was applied to the entire roof at a wet film thickness of 350 microns.Despite the steep pitch of the roof, runoff was not an issue; the product stuck to the roof and did not drip, leaving a consistent, glossy finish that left the whole roof looking like new.Metalseal can be made in more than just the standard goosewing grey - if you have an industrial roof that needs coating, Liquasil can meet your needs - no matter the colour.Give us a call on 0121 709 5352, or email us at info@liquasil.com.

The finish to the asbestos roof and asbestos cladding on this property was faded and the roof leaked in several places, along with the gutter. Liquasil's silicone roof coating, Asbestoseal, was chosen to seal the roof and dramatically improve the aesthetic appearance using specially made RAL colours to the match the original finishes. The asbestos cement gutter was also lined with the Liquasil liquid gutter liner to form a permanent, bonded solution.

Liquasil's BBA Approved Metalseal 20 roof coating and Gutterseal system were specified for use on the Airspace Trampoline Park in Wolverhampton. The whole roof was pressure washed and a historical cut-edge corrosion treatment was removed before application; the cut-edges were treated with our SWT Corrosion Primer, with additional reinforcement to the mid-laps through the installation of Liquasil's optional HP Butyl Tape.The whole roof was then coated with Metalseal 20 in Goosewing Grey at a filmweight of c. 300 microns to provide a protective, aesthetically pleasing finish.The gutters were cleaned out and dried before being primed with our SWT Corrosion Primer. Once touch-dry, the joints could then be sealed using our Non-Sag Sealer and a single coat of Liquasil One was applied to the entire gutter. Liquasil One can be immediately applied over the top of Non-Sag Sealer, meaning no time is wasted waiting for it to cure before the works can continue.The end result was a revitalised metal roof with a protective, water-resistant coating that is guaranteed for 20 years.

The Koster TPO Single Ply membrane was selected to waterproof the flat roof on this new build development. The design called for a warm roof system installed over a timber deck followed by a sedum blanket (on protection membrane).Koster TPO 2mm Fleeceback membrane was used as it is highly resistant against mechanical damage, fully weldable so no weaknesses and it will not contaminate any of the planting such as a PVC membrane would.The Slate Grey RAL 7015 colour was selected to compliment the Zinc cladding.

This was the first asbestos roof coating project undertaken with Liquasil products, back in 2013. The roof was heavily soiled and was cleaned using a DOFF steam cleaning machine, delivering 150°c steam to completely kill moss and lichen spores. The metal fixings were treated with Liquasil's corrosion primer and sealed with Non-Sag Sealer before the whole roof was coated with Asbestoseal, the only BBA Approved asbestos roof coating.

Furnitubes designed and manufactured a number of AKRI retaining steel wall planters with ped and tray system for rooftop scheme in in Bexleyheath, south London. AKRI’s unique ped and tray system allows the planters to be left freestanding, sitting on a layer of waterproof membrane. Decking and pergolas were installed and benches were later retro-fitted to the planters to seamlessly integrate seating, manufactured in all steel to accommodate the required A fire rating, creating stunning landscaped roof tops across both buildings in the heart of a bustling city.

This complicated asbestos roof structure was heavily soiled and leaking in numerous places. Asbestoseal was specified because it is the only BBA Approved asbestos roof coating on the market. The roof was cleaned using 150°c steam, which kills all moss and lichen spores on contact, leaving a perfectly clean substrate for coating. The success of any coating comes from its preparation and Liquasil teaches all of it approved installers various cleaning methods. The roof was coated and is now leak free with a much extended life expectancy.
